TLC spot extraction

I am wondering what is the best method to use to extract a compound that is separated by TLC by the liquid extraction method following spot isolation (visualization using UV and scraping absorbent silica from plate) for identification by UV spectroscopy.

I originally used methanol for extraction of the unknown compound and analyzed solution with plain methanol for the reference solution. Problem is that I read that methanol dissolves silica gel. I assume that this would affect the spectra? (not sure how)

1. Assuming that it would affect the qualitative identification of a compound by UV , would the problem be solved by using a reference solution of methanol (after using it to 'extract' silica scraping from part of plate without desired compound).

Or should I just use ethanol, separate extract, dry and then redissolve residue in whatever solvent I need compound to be in?

2. Second issue is that I need the compound in different pH solutions (10 & 2). Could I use the acidic/basic aq solutions for extracting silica or would that dissolve it as well ? From what I read, extreme pH will dissolve the silica gel coating. Is the solution for this to also extract using a volatile solvent (having trouble picking one that will leave gel and extract out compound), drying, and redissolving it at needed pH?

I was going to try what you mentioned from a practical point but was wondering if anyone knew about this.

Also, what about my second dilemma regarding extraction to solutions of different pH and effect on the silica gel? Would I have to use organic solvent to extract, dry the solvent and then redissolve compound in aqueous base/acid solution?
